流の偏向発振を行おうとするものである。As a result, the main jet from the supply nozzle /L/16
Since the oscillating jet signal transmission flow path is provided in which 7.18 is attached and ejected alternately, this flow path may become blocked and malfunction may occur, and the oscillation may be affected by the feedback port and feedback flow path conditions. As a result, the design tolerance for stable oscillation is extremely narrow, making it difficult to manufacture stable devices. It consists of a nozzle, an induction chamber with an opening communicating with the atmosphere, and a side wall, and is intended to deflect and oscillate the jet stream.

噴射させる。The low pressure generated when the jet stream ejected from the supply nozzle of the working element passes through the induction chamber attracts air from the atmosphere, and the action of the air flowing into the induction chamber generates a pressure difference between the left and right induction chambers. The jet stream is pre-directed, and the jet stream is further deflected by the wall effect of the adhesion wall to cause the jet stream to be injected from the injection port.

11.12 is an induction chamber having a gas inlet 9 communicating with the outside and having a downstream end shaped like a constriction part 10;
The side walls 13 provided on both downstream sides of the side walls 11 and 12 are jet ports formed at the downstream opening ends of the side walls 11 and 12. Also, the side wall 11.

射流Fi1の両側に気体筒vL1、VL2を形成する。The liquid that has flowed into the supply channel 6 is injected from the supply nozzle /L/7. Since this jet stream becomes a high-speed flow in the induction chamber 8, the pressure in the induction chamber 8 becomes lower than atmospheric pressure. That is, since the pressure becomes negative with respect to the atmosphere, air is induced into the induction chamber 8 through the gas inlet 9, forming gas cylinders vL1 and VL2 on both sides of the jet flow Fi1.

上第5図に示す状態となる)。The pre-directed jet flow Fi1 passes through the constriction section 10 and the jet flow F4
A low-pressure vortex AL1 is generated due to the wall effect between 1 and the side wall 11, and it adheres to or almost adheres to the side wall 11, is deflected by the upper side, and is ejected from the ejection port 13 as F, 1 (as shown in Fig. 3). ). Next, a part of the gas cylinder VL2 formed by the jet flow Fi2 flows out of the induction chamber 8 together with the jet flow F2 as bubbles B, flows into the low pressure vortex Al1 part, and flows between the jet flow Fi2 and the side wall 11. Destroy low pressure conditions. As a result, the jet flow Fi2 separates from the adhesion wall 11,
The jet stream F02 moves straight and is jetted out from the spout 13 (the state shown in FIG. 4 is thus reached). Next, due to the inertia and jet instability that occur during jet adhesion and separation, the jet flow Fi3
adheres to the opposite side wall 12 and generates a low-pressure vortex AR3, which adheres to or almost adheres to the side wall 12, is deflected by the lower side, and is ejected from the jet nozzle 13 as F03 (the above state shown in Fig. 5). ).
以後、上記側壁11側で説明した付着剥離現象が付着壁
12側で発生し、噴射流は側壁11.12間を交互に付
着した発振流となる。Thereafter, the adhesion separation phenomenon described on the side wall 11 side occurs on the adhesion wall 12 side, and the jet flow becomes an oscillating flow that adheres alternately between the side walls 11 and 12.
